My Samsung laptop is flaking out!

My Samsung laptop had started flaking out the last week or two - stalling, freezing, giving me weird color shades occasionally, and taking forever to open programs sometimes. I'm afraid that the OS may be bad, but I also don't know if it may be a hardware issue, either.

I recently put a friend's Windows 7 OS on this laptop (Windows version 6.1). I had to reinstall all the drivers again - maybe I missed something?

Any help appreciated. I once lost the contents of a computer completely, so I don't want that to happen again.

I got another blue screen of death. It said "Page Fault in Nonpaged Area" - something like that. Unfortunately, I never configured a restore point on the computer to revert back to. I did a fix or something in the menu when rebooting and pressing F8.

When your system BSODs, write down the STOP error code, as well as any written out error message back here. The STOP error will always appear, but the message may not. You are looking for this:

Please post me the error(s).

I'll do this as soon as I get home, thanks.

Is the STOP error code the entire series of numbers on the STOP line or just the last set? I'd have to do a Print-screen to get them all in time - assuming that function would work when getting the blue screen of death.
